One hundred and fifty-seven cases of Graves' disease were divided into three groups according to their clinical features and thyroid functions: Group A, untreated; group B, treated but uncontrolled or relapsed; group C, treated and remitted. The positive rates of TSH receptor antibody (TRAb), anti-tnyroglobulin antibody (TgAb), anti-microsomal antibody (TmAb), anti-DNA antibody and anti-nuclear antibody (ANA) were 91.2, 79.4, 79.4, 70.6 and 23.5% respectively in group A. The positive rate of TRAb and TBII were significantly different between group C and group A or B (both P

Objective: To explore the relationship between plasma levels of soluble receptor of advanced glycation end products (sRAGE), brain natriuretic peptide (BNP) and cardiac function in patients with sepsis.
Methods: A total of 83 sepsis patients treated in our hospital from 2014-01 to 2015-06 were studied. Plasma levels of sRAGE, BNP were examined at 24 h after admission and they were evaluated by APACHEII scores. According to BNP levels, the patients were divided into 2 groups:Normal cardiac function group, the patients with BNP<500 pg/ml, n=32 and Cardiac dysfunction group, the patients with BNP≥500 pg/ml, n=51. The cardiac function as stroke volume (SV), LVEF, minute volume, E/A were examined by echocardiography. The above indexes were analyzed and compared between 2 groups, the relationship between plasma levels of sRAGE and the occurrence of sepsis was assessed by Logistic regression analysis.
Results: Compared with Normal cardiac function group, the patients in Cardiac dysfunction group presented decreased SV, LVEF, minute volume and E/A;increased APACHEII scores and sRAGE, all P<0.01. Plasma levels of sRAGE in sepsis patients were positively related to BNP (r=0.90, P<0.05) and APACHEII scores (r=0.85, P<0.05). Logistic regression analysis indicated that plasma levels of sRAGE (OR=1.019, 95%CI 1.004-1.035, P<0.05) was independently related to cardiac function in patients with sepsis.
Conclusion: Plasma levels of sRAGE were independently related to cardiac function in patients with sepsis.

Objective To investigate the situation and change of antifungal resistance in clinical Candida and other fungal iso- lates from 5 hospitals in diverse geographic region of China.Methods Antimicrobial susceptibility testing of 8 000 fungat iso- lates collected during 2001 and 2005 were carried out with 25?g fluconazole disk and 1?g voriconazole disk using disk diffusion method as recommend by CLSI/NCCLS M44-A.Disk test plates were automatically read and results were recoded with the BIOMIC Image Analysis System.The equivalent MICs were automatically calculated by the BIOMIC System software.Results The proportion of Candida atbicans and non-Candida albicans (e.g.Candida glabrata) in the total fungal isolates did not change significantly from 2001 to 2005.The susceptibility rate of C.albicans to fluconazole and vorieonazole were stable during 2001 and 2005.However, the resistance to fluconazole and voriconazole increased variably in C.glabrata and other non-Can- dida albicans fungal isolates during the same period.Conclusions The voriconazole demonstrated higher activity against all yeast species in comparison with fluconazole.The increasing resistance to fluconazole and voriconazole in non C.albicans fungal isolates including C.glabruta suggests the importance of surveillance of fungal resistance in Candida isolates.

To optimize the growth condition for the established gene engineer bacteria express cardiac troponin-I(cTnI) and to obtain purified cTnI as an antigen to produce clinical assay kits used in acute myocardial injury(AMI) diagnosis.Plackett Burman Design(PBD) was applied to select the factors which effect the expression of cTnI in Escherichial coli(E.coli) mostly.Induction time,pH and KCl were proved influenced expression of cTnI notably.Afterward,Response Surface Methodology(RSM) as second step to optimize the selected three factors,an equation was deduced to predict the percent of cTnI.In the most optimized condition,the percent of cTnI can reach to 26% of total cell protein.The procedures of purification included ammonium sulfate deposition and DEAE Cellulose ion exchange chromatography.SDS-PAGE shows that purified cTnI contain one band.cTnI could be used to immune animals as an antigen to produce monoclonal antibodies with high affinity and specificity.It maybe as calibrators to harmony the difference assays of cTnI measurement in clinical.
